Paper Abstract
High noise values and poor signal to noise ratio are traditionally associated to the low light imaging. Still, there are
several other camera quality features which may suffer from low light environment. For example, what happens to the
color accuracy and resolution or how the camera speed behaves in low light? Furthermore, how low light environments
affect to the camera benchmarking and which metrics are the critical ones?
The work contains standard based image quality measurements including noise, color, and resolution measurements in
three different light environments: 1000, 100, and 30 lux. Moreover, camera speed measurements are done. Detailed
measurement results of each quality and speed category are revealed and compared. Also a suitable benchmark algorithm
is evaluated and corresponding score is calculated to find an appropriate metric which characterize the camera
performance in different environments.
The result of this work introduces detailed image quality and camera speed measurements of mobile phone camera
systems in three different light environments. The paper concludes how different light environments influence to the
metrics and which metrics should be measured in low light environment. Finally, a benchmarking score is calculated
using measurement data of each environment and mobile phone cameras are compared correspondingly.
